He just sounds like he's really bad at texting, I've had the same problem. Thats a huge pet peeve of mine is when they text you first but can't bother to keep it going. I eventually gave up and got annoyed because he wasn't putting in the effort. If you really like him , you can always ask what he's doing one weekend and go from there.
He probably does want to talk to you, but if you're interested in him, consider asking him out yourself. Or if you're one of those females who stick to the old, outdated, 17th century rule of men always making the first move, then you're gonna have a pretty hard time with this guy while you wait for him to ask you out.
